PURCELL PRUSIKS

A set of personally-sized Purcell Prusiks
can provide a rescuer with a readily-
accessible and inexpensive means to
ascend a fixed rope. The added
functionality of Purcell Prusiks for
numerous other uses makes them
essential for every rescuer. The Purcell
Prusik System was developed by the
Columbia Mountain Rescue Group in
69
British Columbia. The three
components of the system include a
Long Foot Prusik, Medium Foot Prusik
and a Short Harness Prusik (Figure
149). The two Foot Prusiks permit easier
movement in non-free hanging terrain
(e.g. steep slab of rock). Additionally, if
one Foot Prusik is being employed as an
adjustable attachment (e.g. litter
attendant), then the other Foot Prusik
can still be used to ascend a short
distance, if necessary. The traditional
Purcell Prusik Ascending System
does not meet the requirement for
two points of attachment above the
waist. This shortcoming can be
overcome by incorporating an additional
safety tether to the harness from one of
the Foot Prusiks.
